Presence LOUDSPEAKERS FOR TODAY'S ARCHITECTURE A-120 300 Watt Powered Subwoofer FEATURES » The A-120 subwoofer was designed for exceptional performance and value. It features a 12" extra-long excursion woofer with high BL motor. The bass reflex enclosure with flared port ensures extended bass response and high acoustic efficiency. » The woofer is driven with an integral 300W class A/B amplifier utilizing the patented BASH® technology for high electrical efficiency. » The integral rear-mounted 300 watt amplifier includes level, phase (continuously variable 0-180°), and crossover control to contour the subwoofer’s output to blend with virtually all loudspeakers and room environments. » The integral low pass crossover network is continuously-variable from 40Hz to 120Hz and can be bypassed if it is preferable to use an external crossover located in an outboard receiver or processor. » The A-120’s integral amplifier incorporates a defeatable signal-sensing circuit that automatically powers up the amplifier when a signal is detected. » A double-insulated isolated-ground electrical supply prevents electrical ground loops and reduces the noise floor of the entire audio system. 12" EXTRA LONG-THROW Heavy Duty Driver ISO 9001 Registered Factory Weleome Home Ww, OEM SYSTEMS COMPANY (775) 355-0405 + (775) 355-0646 www.
